✅ 4.0 out of 5 stars
"I bought this for my class ring, and it works excellently. It's nearly invisible when worn, and the soft plastic helps keep my ring from moving around. If you have larger knuckles, this is perfect because it keeps the ring secure without cutting off circulation! The only downside is that you should use the small adhesive strips to prevent scratching on gold rings."
